Short and sweet: how to choose a RAID/HBA controller for the server
RAID controllers have not left and are not going to, on the contrary, hardware controllers for NVME and PCI Express drives (including M2 format drives) are entering the market. The abundance of drives and software features of RAID/HBA make you approach this choice as responsibly as possible, otherwise you may lose data.

Putting the cables in order in the server room. Where to start and what will be required
Careful laying of cables in the server rack is especially important to ensure ease of maintenance of IT equipment and to give a professional look to your server cabinet. Many organizations face difficulties when servicing a large number of cables, especially if they are not marked and everything is the same color as for evil. It is recommended to plan the cabling in advance before starting the installation and organization of the rack. If the cables were connected before the organization, then ...
Server rack monitoring: what is needed for this
Technologies are so advanced today that there are many tools for monitoring server racks and the entire computing infrastructure of a small enterprise. These systems also allow you to optimize energy use, manage backup power and control cooling.
A server rack is a miniature ecosystem with its own climate, its own electrical part, as well as its own security and protection facilities. But how to ensure the proper functioning of the rack and early troubleshooting? The solution is monitoring ...
Guide to patch panels
Patch panels differ in the principle of installation, design, shielding and other parameters. Today it is already a mandatory attribute of a server rack or a switching cabinet, so you need to know everything about them!
Patch panels are tools for organizing and managing connections between computers, switches and other equipment in a LAN. They are designed to facilitate access to network cables, simplify the marking of inputs, increase the reliability of network connections and simplify work ...
Server fans: what they are, how they work
Server fans play a key role in maintaining the temperature at an optimal level. They operate at high speeds to ensure sufficient airflow within the server system, thereby cooling it. Most server fans are designed to operate at different speeds, which significantly enhances their efficiency. This means that when the server system is under load, the server fans operate at higher speeds to increase cooling, and when the load is light, the speed decreases.
The main function of server fans is to ...
Lenovo ThinkAgile VX3320 review - a hyperconverged solution for simplified enterprise-wide vSAN deployment
Hyperconverged systems are rapidly gaining popularity and are already becoming the standard for building virtualization platforms in the corporate environment. Lenovo has released a special series of servers for installing and running VMware vSAN with tools for simplified administration and deployment at the customer's facility.
The ideology of hyperconvergent solutions using VMware technologies has its advantages: this is a relatively low cost at the start, and the ability to scale almost ...
Review of Lenovo ThinkEdge SE50 and SE30-industrial and peripheral PCs based on Core i7 with passive cooling
These are universal computers that can simultaneously be used in production, at peripheral facilities, and are equally well suited for PC-controlled equipment, for building control rooms, laboratories, and engineering workplaces. No moving parts concept, 4G/LTE support with eSIM, DIN rail mount and RS232 ports.
The development of robotics and automation of workplaces today has led to the fact that the OT industry (short for operational technologies), which includes a system for receiving ...
Review of the 4-CPU Lenovo SR860 V2 server based on Intel Xeon Cooper Lake
A very interesting server with a price of $ 1M, created for SAP HANA and applications with high RAM consumption. Here, the processors are located one above the other, there are 3 TB of memory, 4 power supplies, monitoring with predictive analysis of breakdowns and 48 storage slots.
Today we are testing a very special server from the family of vertically scalable x86 systems. The Lenovo SR860V2 quad-processor is designed to handle mission-critical workloads such as transactional and resident ...
Article about vertical wall-mounting of servers
An interesting solution for home laboratories, small test rooms or maintenance-free points where 1-2-3 pieces of equipment are placed, and every square centimeter is worth its weight in gold
I often came up with the idea: why not place servers vertically, because if you do not have a special server rack, but have a 1U-4U machine, and even a full length of 655 mm, then this bandura will take up the entire room, the entire table or rack. No, I'm not saying that server cabinets are outdated and ...
How water displaces air in Lenovo supercomputers
A couple of years ago, the maximum air cooling limit was 600W per unit. Today, it is theoretically possible to divert up to 1.2 kW per unit using air. However, in the future, you will need to allocate 2 KW, and you can't do without liquid cooling.
Today, there is a steady trend to extract the maximum power from each computing unit of the data center. Users want to see more and more local disk storage inside data center nodes, and circulatory data transfer systems that combine cluster ...
